Authorities in Utah are looking for an Arizona couple they believe traveled to their state to find a buyer for the couple's unborn baby.

Why Utah? According to court documents, the couple allegedly sold another one of their children in Utah about three years ago, and the going rate for a baby within the borders of Arizona's northeastern neighbor is about $6,000.

Alison and Gary Stuckey are the parents of at least four children, with one on the way.

According to court documents, the Stuckey's have no parental rights over three of those children. A foster family in Mesa -- with whom the children are currently living -- is in the process of adopting them.
